Critical behavior investigated through magnetocaloric effect in PrSrMnO and Pr (Sr, Ca) MnO manganites

M Hsini, L Ghivelder, F Parisi - Journal of Magnetism and Magnetic …, 2021 - Elsevier
In this work we investigate the critical behavior of two manganite compounds, Pr 0.5 Sr 0.5
MnO 3 (PSMO) and Pr 0.5 Sr 0.41 Ca 0.09 MnO 3 (PSCMO). These are complex magnetic …

Critical behavior at high magnetic fields in LaPr (Ca, Sr) MnO manganites

M Hsini, L Ghivelder - Physica B: Condensed Matter, 2021 - Elsevier
In this work, we demonstrate that La 0.225 Pr 0.4 (Ca 1− x Sr x) 0.375 MnO 3 manganites
with 0≤ x≤ 0.10, exhibit a discontinuous first order ferromagnetic-paramagnetic transition at …

Thermal cycling effects on static and dynamic properties of a phase separated manganite

J Sacanell, B Sievers, M Quintero, L Granja… - Journal of Magnetism …, 2018 - Elsevier
In this work we address the interplay between two phenomena which are signatures of the
out-of-equilibrium state in phase separated manganites: irreversibility against thermal …
